So I stumbled across this Australian programmer who talks about
branchless programming and assembly-level optimisations, and it's
interesting because he points out the pitfalls of trying to out-optimise
the compiler. Just a random thing I thought the compiler developers
might be interested in.

P.S. The "smaller" function he illustrates, which is essentially "min",
I think FPC already optimises it with a CMOV instruction!
